By Threema GmbH (Kasper Systems GmbH)

Threema is the world’s favorite secure messenger and keeps your data out of the hands of hackers, corporations and governments. Threema can be used completely anonymously, allows to make end-to-end encrypted voice calls, and offers every feature one would expect from a state-of-the-art instant messenger.

Threema is designed to generate as little data on servers as possible – this is a core part of our concept. Group memberships and contact lists are managed on your device only, and never stored on our servers. Messages are immediately deleted after they have been delivered. Local files are stored encrypted on your mobile phone or tablet. All this effectively prevents the collection and misuse of your personal information, including meta data.

Threema encrypts ALL your communications END-TO-END including messages, voice calls, group chats, media files and even status messages. You can rest assured that only the intended recipient can read your chats, and nobody else – not even us. Threema uses the trusted open source NaCl cryptography library for encryption. The encryption keys are generated and safely stored on user’s devices to prevent backdoor access or copies.

Threema is not only an encrypted and private messenger but also versatile and feature-rich.

• write text and send voice messages
• make voice calls (requires iPhone 5s / iOS 9 or above)
• share videos, pictures and locations
• send any type of file (pdf, animated gif, mp3, doc, zip, etc.)
• create groups
• conduct polls with the unique poll feature
• choose between a dark and a light theme
• quickly and silently reply with the unique agree/disagree feature
• verify the identity of a contact by scanning their personal QR code
• use Threema as anonymous instant messaging tool
• synchronize your contacts (optional)

Each Threema user receives a random Threema ID for identification. A phone number or email address is not required to use Threema. This unique feature allows you to use Threema completely anonymously – no need to give up private information or to open an account.

We let users confirm trusted contacts with a QR code or a key fingerprint to prevent man in the middle attacks.

We are a 100% independent and self-financed company in the heart of Switzerland with its own servers and in-house software development. Switzerland is a country with some of the most user friendly privacy laws in the world.

The best in the market

Could be 5 stars (2.9.0)
4/6/2017 5:14:26 AM 2/5 By kingfish66
Audio sounds great but there's two things that ruin the app for me first is no Bluetooth support, yea that Bluetooth headset will not record for this app, you can listen on Bluetooth but you can transmit using it, the second thing is no continuous playback, I'm in a group that posts a lot and I'm an interstate trucker so the idea of clicking on every message to listen to it is to distracting while driving and extremely time consuming, fix those two issues and I'm in for 5 stars

If you care about privacy use this app (2.8.0)

The application offers anonymity and security. It does not link to a phone number or email. It uses a separate key.

Great private messaging app! (2.8.0)

I love this app and love the focus on security. It's recently become one of my favorite apps and I want to convince more people to use it.

Love the security (2.8.0)

I am very security oriented and I enjoy this app. I do agree that no being able to backup more than 20MB is frustrating, but the privacy and security is worth the wait for that to be fixed. I also enjoy that this app can be separately locked unlike just about all of the other messengers out there. And I like that the accounts are NOT going to get purged if they are over a year old and have no activity.

The Best Secure Messenger of All! (2.8.0)
1/2/2017 8:31:10 AM 5/5 By <unavailable>
Threema offers the best security of any encrypted messaging app available! Not only is it based in the pro-privacy country of Switzerland, but it has also been comprehensively audited by a reputable Swiss security firm and found to have no vulnerabilities. The other great thing that makes it unique is that only you have access to your private key and you can exchange public keys directly with friends and family, which proves the identity of your contacts. This robust authentication protects your communications to a greater degree than similar apps. For more confirmation, check out past Security Now podcasts for why Threema is the best messenger you can get. If you are looking for a messaging app that gets security right, look no further than Threema.
